FOR PAY - Contact us for a quotation

Automatic access to satellite-derived solar radiation database HelioClim-3 Current Day. It provides HelioClim-3 version 4 radiation values updated in real time, and forecasts until the end of the current day using a model of persistence. Please for a quotation and receive your SoDa credentials. This type of access is particularly well-suited for monitoring applications.

Automatic access to HelioClim-3 together Meteo variables is also described ("+Add Meteo" option). Meteo variables are extracted from GFS (NCEP).

Warning! It is strongly recommanded to avoid the launch of parallel requests, using the "&" at the end of each wget request line. This would endanger our system.

Automatic access with WGET

In brief, as soon as a new Meteosat image is available every 15 min, the HelioClim-3 database is updated in real time. To receive a time series covering the whole current day, we decided to complete the time series by applying a persistence model.
